Tepitoopit

Tepitoopit is a fictional mineral widely used in speculative fiction and educational exercises to illustrate mineralogical concepts. It is not recognized by scientific bodies.

In fictional sources, Tepitoopit is described as a rare phosphate-silicate mineral with a high refractive index and a shimmering, variable color. The assumed chemical composition and crystal system vary by author, with some attributing a hexagonal habit and a generalized formula TpSiO4 with trace metal substitutions.

Etymology and usage: The name Tepitoopit has appeared in diverse works and is typically treated as a plot device to explore scarcity, trade, and technological value. In pedagogy, Tepitoopit serves as a placeholder to discuss mineral classification, Mohs hardness, and geochemical processes without using real minerals.

Occurrence: In fiction, Tepitoopit is said to form in high-temperature hydrothermal systems or ultramafic rock environments; some narratives place it in meteorite or asteroid contexts. No physical specimens exist outside fictional narratives, and its properties vary across universes or authors.
